For obtaining the high-precision motion parameter, MP1 obtains unit 22 from 21 that provide from HDD144 through input/output interface, as to have high frame frequency and high definition HD image detection (calculating), and obtain kinematic parameter MP1 thus, such as motion vector, and kinematic parameter MP1 offered multiplexer 24.Because MP1 obtains unit 22 and use the HD image that has write down on HDD14, detects kinematic parameter MP1, therefore can use for example a large amount of frames, obtain high-precision motion parameter MP1.

More particularly, for example relevant with the motion vector among the kinematic parameter MP1, under situation,, carry out and handle by using two or three frames based on the image processing of MPEG (Motion Picture Experts Group) standard, detect motion vector.In contrast, because MP1 obtains unit 22 by the HD image detection motion vector that has write down on HDD14, compare with the situation of real-time detection motion vector, the enough time can be used.Therefore, can use four or above frame, detect motion vector.This is used for predicted motion trend more accurately, thereby obtains high accuracy motion vectors.

Remove as mentioned above, through input/output interface 21, the HD image that provides from HDD14 obtains outside the kinematic parameter MP1, and MP1 obtains unit 22 the HD image is offered withdrawal device 23.

The frame of the HD image that provides from MP1 acquisition unit 22 is provided withdrawal device 23, or the pixel of each frame, the HD image transitions is become the abstract image of being made up of low volume data, and abstract image is offered multiplexer 24.

More particularly, for example, withdrawal device 23 is carried out and is extracted so that the n of an every HD image successive frame, and deletion N-1 frame, N be more than or equal to two, thereby HD image transitions one-tenth is had than the HD image abstract image of low frame rate more.In addition, for example, withdrawal device 23 is carried out and is extracted so that N neighbor of each frame in the successive frame of HD image reduced to a pixel, and M is more than or equal to 2, thereby HD image transitions one-tenth is had than the HD image abstract image of low resolution more.

In addition, withdrawal device 23 can extract the frame of HD image, and the pixel that extracts each frame, thereby the HD image transitions is become the abstract image of being made up of low volume data.

Multiplexer 24 multiplexing by MP1 obtain the unit 22 that provide, as the kinematic parameter MP1 of moving parameter information and the abstract image that provides by withdrawal device 23, and final multiplex data offered input/output interface 21.

Input/output interface 21 will offer HDD14 by the multiplex data that multiplexing moving parameter information and abstract image in multiplexer 24 obtain, so that multiplex data is recorded on the HDD14.

MP1 obtains unit 22 and can carry out and be used for directly from through input/output interface 21, and the HD image that provides from HDTV video camera 12 (rather than be recorded on the HDD14 HD image) obtains the processing of kinematic parameter MP1.

Multiplexer 24 can with obtain from MP1 the unit 22 that provide, as the kinematic parameter MP1 of moving parameter information, and directly offer input/output interface 21 from the abstract image that withdrawal device 23 provides.

In this case, for example, input/output interface 21 is non-multiplexing moving parameter information and the abstract image that is provided by multiplexer 24, as independent file storage at HDD14.

Then, will performed processing in the recording controller 13 shown in Figure 2 be described with reference to flow chart shown in Figure 3.

When the HD image has been offered recording controller 13, recording controller 13 receives the HD image and the HD image is offered HDD14, so that the HD image is recorded on the HDD14.Then, recording controller 13 is according to flow chart shown in Figure 3, carry out and handle, for example, when the user on the operating unit (not shown) during executable operations or when there is not pending processing in (in fact).

More particularly, input/output interface 21 reads the HD image and this HD image is offered MP1 from HDD14 and obtains unit 22.In step S11, the HD image of unit 22 from being provided by input/output interface 21 is provided MP1, obtains kinematic parameter MP1, and this kinematic parameter MP1 is offered multiplexer 24.Simultaneously, MP1 obtains unit 22 and will offer withdrawal device 23 from the HD image that input/output interface 21 provides.Then, processing enters step S12.

At step S12, the frame of the HD image that is provided by MP1 acquisition unit 22 or the pixel of its each frame are provided withdrawal device 23, thereby the HD image transitions is become the abstract image of being made up of low volume data, and this abstract image is offered multiplexer 24.Then, processing enters step S13.

At step S13, it is multiplexing that multiplexer 24 will obtain unit abstract image 22 that provide, that provide as the kinematic parameter MP1 of moving parameter information and from withdrawal device 23 from MP1, and final multiplex data is offered input/output interface 21.Then, processing enters step S14.

At step S14, input/output interface 21 will offer HDD14 from the multiplex data that multiplexer 24 provides.Then, finish this processing.

Fig. 4 is the block diagram of the exemplary configurations of expression playback controller 15 shown in Figure 1.

The playback instructions that input/output interface 41 response has for example been sent during executable operations on the operating unit (not shown) as the user reads multiplex data from HDD14, and this multiplex data is offered demodulation multiplexer 42.

The multiplex data demultiplexing that demodulation multiplexer 42 will provide from input/output interface 41 is abstract image and moving parameter information, and this abstract image and moving parameter information are offered image processor 43.

Image processor 43 uses the kinematic parameter MP1 of HD images, i.e. the moving parameter information that provides from demodulation multiplexer 42, and carries out image processing on the abstract image that provides by demodulation multiplexer 42, and will offer monitor 16 by the image that image processing obtains.Image processor 43 can be carried out appropriate image processing by high-precision motion parameter MP1 is used for image processing on abstract image, obtain kinematic parameter MP1 from high-quality (high frame frequency and high definition) HD image.

More particularly, for example, image processor 43 comprises denoiser 44 and interpolater 45.To each frame of abstract image, denoiser 44 uses high-precision motion parameter MP1, determines that two field picture has momental moving image or (basically) the nonmotile rest image more than or equal to a certain amount.In addition, when two field picture had been defined as moving image, denoiser 44 only used the image in this frame, carried out noise reduction.On the other hand, when the image with frame had been defined as rest image, denoiser 44 used comprise the theme frame a plurality of preceding and at the image of back frame, carries out noise reduction.In addition, denoiser 44 offers interpolater 45 with the abstract image behind the noise reduction.The brightness that denoiser 44 uses motion vector among the kinematic parameter MP1 for example or expression brightness to change changes, and determines that each two field picture is moving image or rest image.

Interpolater 45 uses for example motion vector from the high-precision motion parameter MP1 that demodulation multiplexer 42 provides, on the abstract image that provides from denoiser 44, in each frame, carry out frame interpolation or pixel interpolating, thereby abstract image is changed high-quality HD image, and this HD image is offered monitor 16.

Then, will the processing of carrying out in the playback controller 15 shown in Figure 4 be described with reference to flow chart shown in Figure 5.

When the image replaying instruction is sent to input/output interface 41, for example, when the user has sent during executable operations on the operating unit (not shown), in step S21, HDD14 reads multiplex data and multiplex data is offered demodulation multiplexer 42 from HDD14.Then, processing enters step S22.

At step S22, demodulation multiplexer 42 will demultiplex into abstract image and kinematic parameter MP1 from the multiplex data that input/output interface 41 provides, and abstract image and kinematic parameter MP1 are offered image processor 43.Then, processing enters step S23.

At step S23, use high-precision motion parameter MP1, i.e. the kinematic parameter that also provides from demodulation multiplexer 42, image processor 43 is carries out image processing on the abstract image that provides from demodulation multiplexer 42, and final image is offered monitor 16.Finish this processing then.

More particularly, in image processor 43, denoiser 44 uses kinematic parameter MP1, carries out noise reduction on abstract image, and will finally reduce image and offer interpolater 45.Use kinematic parameter MP1, interpolater 45 is carried out interpolation, thereby is converted abstract image to the HD image, and the HD image is offered monitor 16 on the abstract image that provides from denoiser 44.The HD image that is provided by this interpolater 45 (image processor 43) is provided monitor 16.

Fig. 6 is the block diagram of another exemplary configurations of expression recording controller 13 shown in Figure 1.

In Fig. 6, corresponding to parts shown in Figure 2 by identical numeral, and will suitably the descriptions thereof are omitted.

Recording controller 13 shown in Figure 6 comprises frame withdrawal device 52, rather than withdrawal device 23, and comprises that newly MP2 obtains unit 53, the MPd difference information obtains unit 54 and compressor reducer 55.Other structures of recording controller 13 shown in Figure 6 are identical with Fig. 2.

Frame withdrawal device 52 obtains unit 22 from MP1 and receives the HD image.The frame of the HD image that provides from MP1 acquisition unit 22 is provided frame withdrawal device 52, thereby the HD image transitions is become the abstract image of being made up of low volume data, and abstract image is offered MP2 acquisition unit 53.

The abstract image of unit 53 from being provided by frame withdrawal device 52 is provided MP2, detect (calculatings), thereby and obtain sports kinematic parameter MP2, such as the motion vector of abstract image, and this kinematic parameter MP2 offered MPd difference information acquisition unit 54.In addition, MP2 obtains unit 53 abstract image and kinematic parameter MP2 is offered compressor reducer 55.

The MPd difference information obtains unit 54 and obtains unit 22 reception kinematic parameter MP1 from MP1, and also obtains unit 53 reception kinematic parameter MP2 from MP2.The MPd difference information obtains unit 54 and detects (calculating), thereby and obtain, and difference information MPd is offered multiplexer 24 with the kinematic parameter MP1 that provides from MP1 acquisition unit and from the relevant difference information MPd of one or more differences between the kinematic parameter MP2 of MP2 acquisition unit 53 acquisitions.

When the parameter of same type is included among kinematic parameter MP1 and the kinematic parameter MP2, if the difference between could calculating parameter, could be with the difference information MPd of the difference between parameter as relevant moving parameter information.When a certain parameter is present among the kinematic parameter MP1 but relevant parameters when not being present among the kinematic parameter MP2, be present in parameter among the kinematic parameter MP1 can be directly as the difference information MPd of relevant moving parameter information.That is, the difference information of relevant kinematic parameter can be arbitrary information, as long as use the difference information MPd of relevant moving parameter information and kinematic parameter MP2, and can reconstitution movement parameter MP1.

As mentioned above, when difference information MPd as moving parameter information, can use the difference between the parameter among kinematic parameter MP1 and the kinematic parameter MP2, or kinematic parameter MP1 itself.Usually, the difference between kinematic parameter MP1 and kinematic parameter MP2 has the data volume still less than kinematic parameter MP1 itself.Therefore, the difference when between kinematic parameter MP1 and kinematic parameter MP2 is recorded on the HDD14, during as moving parameter information, upward compares as the situation of moving parameter information with kinematic parameter itself being recorded in HDD14, saves the memory capacity of HDD14.In addition, can shorten translatory movement parameter information institute's time spent.

In addition, when being used as from the difference of kinematic parameter MP2 the kinematic parameter MP1, only be used in image processor shown in Figure 11 43 in the relevant moving parameter information of one or more kinematic parameter MP1 the time, can further shorten translatory movement parameter information institute's time spent, and the memory capacity that can further save HDD14.

Compressor reducer 55 uses also and obtains the kinematic parameter MP2 that unit 53 provides from MP2, and for example according to the MPEG scheme, compression obtains the abstract image that unit 53 provides from MP2, and final packed data is offered multiplexer 24.

In Fig. 6, the difference information MPd that multiplexer 24 will provide from MPd difference information acquisition unit 54 regards moving parameter information as, the packed data of the multiplexing abstract image that provides as the difference information MPd and the compressor reducer 55 of moving parameter information offers input/output interface 21 with final multiplex data.

Then, will be described in the processing that MPd difference information shown in Figure 6 obtains execution in the unit 54 with reference to figure 7.

For example, suppose by carrying out 1/2 and extract that withdrawal device 52 becomes abstract image with the HD image transitions so that two successive frame frames of HD image are reduced to a frame, and with motion vector as kinematic parameter MP1 and MP2.

In addition, the n frame of the HD image of Ji Suaning will be expressed as the n frame from the outset, and from the n frame to the n ' frame (n '＞n) motion vector will be expressed as motion vector mv (n, n ').

With reference now to Fig. 7,, three successive frames, i.e. n frame, (n+1) frames of relevant HD image, and (n+2) frame, suppose that deletion (n+1) frame is so to this HD image by the HD image transitions being become the extraction of abstract image, detect motion vector mv (n, n+1) and mv (n+1, n+2), and to abstract image, detect motion vector mv (n, n+2).

Motion vector mv (n based on abstract image, n+2), 1/2 of MPd difference information computing unit 54 compute vectors, i.e. 1/2 * mv (n, n+2) as the motion vector mv of HD image (n, predicted value mv ' n+1) (n, n+1) and the motion vector mv (n+1 of HD image, predicted value mv ' n+2) (n+1, n+2).In addition, the MPd difference information obtains unit 54 calculating kinematical vector mv (n, n+1) and predicted value mv ' (n, n+1) the difference mv between (n, n+1)-mv ' (n, n+1), and with difference mv (n, n+1)-(n n+1) is set to motion vector mv (n to mv ', difference information MPd n+1) (n, n+1).Simultaneously, the MPd difference information obtains unit 54 calculating kinematical vector mv (n+1, n+2) and its predictor motion vector mv ' (n+1, n+2) the difference mv between (n+1, n+2)-mv ' (n+1, n+2), and with difference mv (n+1, n+2)-(n+1 n+2) is arranged to motion vector mv (n+1 to mv ', difference information MPd n+2) (n+1, n+2).

Motion vector mv (n by abstract image, n+2), can calculate motion vector mv (n, predicted value mv ' (n n+1) of HD image, n+1), and can (n be n+1) with as difference information MPd (n, difference mv (n n+1) by its predicted value mv ', n+1)-mv ' (n, n+1), and the motion vector mv of calculating HD image (n, n+1).That is, by with the motion vector mv of abstract image (n, n+2) with as difference information MPd (n, difference mv n+1) (n, n+1)-mv ' (n n+1) adds together, motion vector mv that can reconstruct (calculating) HD image (n, n+1).

Similarly, can use abstract image motion vector mv (n, n+2) and as difference information MPd (n+1, difference mv n+2) (n+1, n+2)-mv ' (n+1, n+2), can reconstruct the HD image motion vector mv (n+1, n+2).

MP1 reconstructor 84 shown in Figure 11 as mentioned below is in aforesaid mode, the motion vector mv of reconstruct HD image (n, n+1) and motion vector mv (n+1, n+2).

In Fig. 7, in theory, satisfy equation mv (n, n+1)+mv (n+1, n+2)=mv (n, n+2).In this case, remove abstract image motion vector mv (n, n+2) outside, when two motion vector mv of HD image (n, n+1) and motion vector mv (n+1, but one of n+2) time spent can calculate another motion vector.

Therefore, even as difference information MPd (n, n+1) and difference information MPd (n+1, when n+2) all unavailable, a but time spent in these difference information, can use the motion vector mv (n of this difference information and abstract image, n+2), the motion vector of the HD image that reconstruct is relevant with difference information, and use the motion vector of the HD image relevant and the motion vector mv (n of abstract image with difference information, n+2), the further motion vector of the reconstruct HD image relevant with another difference information.

According to as mentioned above, the MPd difference information obtains unit 54 not necessarily must be with motion vector mv (n, n+1) difference information MPd (n, n+1) and motion vector mv (n+1, n+2) difference information MPd (n+1, n+2), and one of these difference information be enough to as moving parameter information all as moving parameter information.

In this case, with (n, n+1) (n+1 n+2) all compares as the situation of moving parameter information, reduces the data volume of moving parameter information with difference information MPd with difference information MPd.Therefore, can further reduce translatory movement parameter information institute's time spent, and the memory capacity that can further save HDD14.

Then, will further describe in MPd difference information shown in Figure 6 and obtain performed processing in the unit 54 with reference to figure 8 and 9.

In Fig. 8 and 9, similar simultaneously with Fig. 7, only motion vector is regarded as kinematic parameter MP1 and kinematic parameter MP2.In addition, suppose that the HD image is made up of 11 frames, and extract so that the even frame (hereinafter, being called even frame) of deletion HD image that frame withdrawal device 52 becomes abstract image with the HD image transitions by carrying out.In addition, suppose the detection motion vector, relevant first frame to the, six frames from the HD image move up and from the 6th frame to the 11 frames of HD image with the constant speed of a pixel of every frame, the motion object that moves down with the constant speed of two pixels of every frame.

Fig. 8 represents the position with respect to the motion object in first frame, the position of motion object (being called the HD picture position hereinafter) in each frame of HD image, based on predicted position (the prediction interpolation position that is called abstract image hereinafter) at the motion object of former frame to each even frame two odd-numbered frame (being called odd-numbered frame hereinafter) at the HD image of the motion-vector prediction of back one frame from two odd-numbered frame, and the interpolated error of the error between the prediction interpolation position of expression HD picture position and abstract image.

More particularly, in Fig. 8, represent the HD picture position, represent the prediction interpolation position of abstract image, and represent interpolated error by black triangular marker with the black square mark by black circle mark.Although the prediction interpolation position of abstract image exists only in the even frame, in Fig. 8, for simplicity,, also represent the prediction interpolation position of abstract image to odd-numbered frame.

As the prediction interpolation position of the abstract image that is used for even frame, the mean value of the position of the motion object in the odd-numbered frame before and after the use even frame.As the prediction interpolation position of the abstract image that is used for odd-numbered frame, the HD picture position of directly using odd-numbered frame.

Fig. 9 is illustrated in the motion vector of the motion motion of objects in each frame of frame number, HD picture position, expression HD image of the order of each frame in the HD image, as by the predicted position of the motion object in the next frame of the motion-vector prediction of each frame of HD image, the motion vector that is illustrated in the motion motion of objects in each frame of abstract image, expression as by the predicted position of the abstract image of the position of the motion object in the next frame of the motion-vector prediction of each frame of abstract image, the prediction interpolation position of abstract image, and interpolated error.

More particularly, in Fig. 9,, and represent the position of the motion object each frame of HD image from second field on a left side from the frame number of the frame of first field (row) on left side expression HD image.Represent the motion motion of objects vector that each frame to the HD image detects from the 3rd field on a left side, and represent predicted position as the motion object in the next frame of the HD image of the motion motion of objects vector prediction from each frame of HD image from the 4th field on a left side.

In addition, the 5th field is represented the motion motion of objects vector that each frame to abstract image detects from a left side, and represents predicted position as the abstract image of the motion object in next frame vector detection, abstract image of the motion motion of objects from each frame of abstract image from a left side the 6th field.Represent the predetermined interpolation position of abstract image from the 7th field on a left side, and from Eight characters section (first field from the right side) the expression interpolated error on a left side.

In Fig. 8 and 9, as previously mentioned, the prediction interpolation position that is used for the abstract image of even frame be before the even frame and after the mean value of position of motion object of odd-numbered frame.Therefore, when the rapid change of motion object, because this change produces the non-zero interpolated error.

More particularly, in Fig. 8 and 9, the speed of motion object changes in the 6th frame (frame with frame number 6) of HD image, and because this changes ,-1.5 interpolated error occurs.

Obtain the difference information MPd of unit 54 acquisitions corresponding to this interpolated error by the MPd difference information.By using difference information MPd corresponding to this interpolated error and the motion vector that obtains from abstract image (as predetermined interpolation position) from the abstract image of this motion-vector prediction, accurate motion vector that can reconstruct (acquisition) HD image.

Then, will the processing of carrying out in the recording controller 13 shown in Figure 6 be described with reference to flow chart shown in Figure 10.

Because the size (pixel count) of SD image is 1/4 of a HD image, form by 8 * 8 pixels of SD image one macro block of forming corresponding to four 16 * 16 pixels of forming by 8 * 8 pixels that comprise the HD image.

In addition, the motion vector in be made up of 8 * 8 pixels of SD image will be expressed as motion vector mv (X _n), and with four, each piece is made up of 8 * 8 pixels, is arranged in upper left, upper right, the lower-left of respective macroblock of HD image and the motion vector of bottom right and is expressed as motion vector mv (A respectively _n), mv (B _n), mv (C _n) and mv (D _n).

The MPd difference information obtains the motion vector mv (A that unit 104 obtains the HD image _n) and the mv (X of corresponding SD image _n) between difference mv (A _n)-mv (X _n), and with this difference mv (A _n)-mv (X _n) be set to relevant motion vector mv (A _n) difference information MPd (A _n).Similarly, the MPd difference information obtains other motion vectors mv (B that unit 104 obtains the HD image _n), mv (C _n) and mv (D _n) with the motion vector mv (X of SD image _n) between difference mv (B _n)-mv (X _n), mv (C _n)-mv (X _n) and mv (D _n)-mv (X _n), respectively as relevant motion vector mv (B _n) difference information MPd (B _n), relevant motion vector mv (C _n) difference information MPd (C _n) and relevant motion vector mv (D _n) difference information MPd (D _n).

Motion vector mv (X by the piece that will form by 8 * 8 pixels of corresponding SD image _n) and as difference information MPd (A _n) difference mv (A _n)-mv (X _n) be added to together, can reconstruct the motion vector mv (A of (acquisition) piece of forming by 8 * 8 upper left pixels of the macro block of HD image _n).

Similarly, use the motion vector mv (X of SD image respectively _n) and as the difference mv (B of difference information MPd _n)-mv (X _n), mv (C _n)-mv (X _n) and mv (D _n)-mv (X _n), the motion vector mv (B of energy reconstruct HD image _n), mv (C _n) and mv (D _n).

As described below, MP1 reconstructor 125 shown in Figure 16 is used the motion vector mv (X of SD image _n) and with the motion vector mv (A of this HD image _n) relevant difference information MPd (An), the motion vector mv (A of reconstruct HD image _n), as mentioned above.Similarly, MP1 reconstructor 125 is used the motion vector mv (A of SD image respectively _n) and difference information MPd (B _n), MPd (C _n) and MPd (D _n), the motion vector mv (B of reconstruct HD image _n), motion vector mv (C _n) and motion vector mv (D _n).
